Data from 300 studies published in four research journals in 2010-2011 were analyzed to assess whether nurse researchers continue to oversample females. One-third of the studies had samples that were 100% female and, on average, 74% of all study participants were female. As was found for studies published 5 years earlier, the bias against male participants was consistent across studies differing in methods, specialty areas, funding, and sample characteristics. Studies with male first authors, however, were significantly less likely to have biased samples. Authors of only 23.6% of studies with mixed-sex samples provided information about sex differences in outcomes. Because of gender bias, the evidence base for nursing practice may suffer from problems with generalizability.
分析了 2010-2011 年在四个医学研究期刊上发表的 300 项研究的数据，以评估护士研究人员是否继续过度抽样女性。三分之一的研究样本全部为女性，平均而言，所有研究参与者中有 74%为女性。与 5 年前发表的研究一样，即使在研究方法、专业领域、资金和样本特征存在差异的情况下，对男性参与者的偏见仍然存在。然而，第一作者为男性的研究，样本存在偏差的可能性显著降低。仅有 23.6%的混合性别样本研究的作者提供了有关结果中性别差异的信息。由于性别偏见，护理实践的证据基础可能存在普遍性问题。
